Medium Wheel Dozers (Non Current)

Every operation is looking for high production support machines. Cat wheel dozers combine the production capabilities of track-type tractors with the mobility and versatility of wheel loaders to give you an outstanding utility machine.

834B Wheel Dozer

The 834B is designed and built for high production dozing applications such as stock pile facing and job site clean up. Rubber tires leave minimal impressions on the ground surface and allow the machine to travel with more mobility, maneuverability and greater speed.

Power Train

Cat power train components provide maximum productivity.

3408E Engine

Caterpillar 3408E Engine utilizes the Hydraullically actuated, Electronically controlled Unit Injector (HEUI) fuel system and Electronic Control Module (ECM) to deliver power and efficiency in the most demanding applications.

Decreased Smoke

High injection pressures, independent of engine speed, decrease smoke and emissions while improving response.

Injection timing

Injection timing and duration are variable to improve fuel efficiency, improve cold starting and decrease smoke and emissions.

Injection rate shaping

Injection rate shaping reduces emissions and reduces engine noise.

Mechanical parts

Reduction in mechanical parts, improves reliability.

Electronic control

Electronic control on the 3408E engines provides many benefits:


Aftercooler cools inlet charge temperature to increase power while reducing thermal stresses that can cause premature wear of pistons, rings and liners.


Oil-cooled pistons and full-length, water-cooled cylinder liners deliver maximum heat transfer for longer component life.

Engine oil cooler

Engine oil cooler maintains optimum oil temperature for proper cooling and longer lubricant life.


Planetary Power Shift Transmission.

Torque Converter

Heavy duty torque converter is designed to transfer maximum available torque from the engine to the transmission, allowing the 834B to easily move through stockpiled floor material, mine face clean up, mine road maintenance and general earthmoving.


New axle-shaft, oil-disc brakes are fully hydraulic, completely sealed and never need adjustment.


Axles are high capacity bevel gear sets and differentials use new gear cutting process for increased strength, providing long life in high duty cycle application. New cutting process also reduces gear noise.

Operator's Station

Comfort and convenience contribute to productivity.


Air conditioned, sound suppressed cab with Rollover Protective Structure is resiliently mounted to reduce sound and vibration.

Air filtration

Air pressurization and filtration provide fresh, clean air for the cab.


Operator sits high in the cab for excellent visibility.


12-volt converter with power lines for radio.

Steering column

Multiple-position, adjustable steering column puts steering wheel and transmissionlever within easy reach.

Flow-amplified steering

Flow-amplified steering delivers responsive, precise control with automotive "feel."

Contour Series Seat

Caterpillar Contour Series Seat is ergonomically designed, variably adjustable, and provides greater operator comfort.


Multiple box-section construction with heat treated moldboard and DH-2 steel cutting edges and end bits to prolong blade life.

Fast production dozing

Fast production dozing in stockpiled material and general earthmoving.

Operator controls

Two levers at operator's right control dozer lift, tilt and tip.

Complete unit

Complete unit consists of blade, push arms, dozer-length skid plate with replaceable wear plates, reversible cutting edges, self-sharpening end bits, hydraulic lines guard and hydraulic lift, tip and tilt cylinders.


Simplified service means more productive time.

Service features

Many convenient service features keep the Cateprillar 834 Wheel Dozer on the job.
